How to avoid the increase of impurities and further purify impurities during the reduction of tungsten powder is a very important task.

The production of ultra-thick tungsten-based hard alloys requires high-quality, ultra coarse tungsten carbide powder raw materials.

Spherical tungsten carbide powder is an important thermal spray material and is playing an increasingly important role in various industries such as electronic information, metallurgy, and machinery.

Spherical tungsten carbide powder is an important raw material for thermal spraying. Some scholars have proposed an improved method for the manufacture of spherical tungsten powder:

Tungsten has an atomic number of 74 and a density of 19.35g/cm³. It has good radiation shielding properties and does not generate secondary electron radiation. It is ideal for nuclear radiation shielding materials. The tungsten shield preparation are as follows:

In the field of hard alloys, coarse-grained carbides have a series of advantages such as less structural defects, high micro-hardness and low micro strain. It is widely used in rock drilling tools, oil drilling tools, stamping dies, wear-resistant and corrosion-resistant parts, high temperature and high pressure endurance, metal pressure processing tools, rolling rings for steel rolling, and hard surface materials.

Waste tungsten oxide including unqualified blue tungsten oxide and tungsten trioxide. Ammonium tungstate includes ammonium tungstate solution, ammonium paratungstate, ammonium metatungstate etc.

Cerium tungsten alloy wire is a promising electrode material. Compared with traditional thorium tungsten alloy wire, cerium tungsten wire has the advantages of low electron emission work, high emissivity, high luminous efficiency and low arc voltage. The most important thing is that there is no radioactive contamination. It is the general trend to replace thorium tungsten alloy wire.

Tungsten has good electrical conductivity, escaping work near the silicon band gap and excellent thermal stability. It has become the first choice material and is widely used in grid materials and wiring materials of integrated circuits.

Organic hydrazine tungstate, the formula is 5(N₂H₅)₂O•12WO₃(also call auto reducing tungstate, abbreviated as ART). Ultrafine tungsten powder can be prepared by hydrogen reduction using ART. In solutions containing tungstate, the generation of ART is based on the following reactions:
